Design concept and solution:Immersed in a sloping dune landscape, the design deconstructs a rectangular box and recomposes it into a house of three levels with a system of routes and living spaces, as well as access to the outside from all levels. The main floor, with kitchen, living, and dining spaces, is designed around a patio, and hovers above a dip in the dunes on the east side, while a stairway on the west side lets you walk down into the sand. Below that main level, half sunk into the dunes, is a concrete basement with a garage and the house’s main entrance. This bunker level also contains a guest apartment with its own separate entrance. A master bedroom suite, with a terrace and access to a rooftop deck that offers views to the sea, occupies the third level. All three stories have rooms connected by multiple hallways that reveal views to the landscape.
